Here's another supernova, this time in the spiral galaxy NGC 3147 a whopping 130 million light-years from us. Similar to the one in my previous photo, this one, SN 2021hpr, is also Type Ia, a "standard candle" some 5 billion times as bright as the Sun, which is why we can see it so far away. Kinda boring photo but pretty cool phenomenon.
Looks like the brightness currently is at about magnitude 15, by comparing to the known brightness of other stars in the frame. Several other galaxies are also in the image, though most are very faint and don't appear in the most familiar catalogs (Messier, NGC, IC) except for one: UGC 5570. Also a couple of stars in our Galaxy are bright enough to be in the HD catalog of bright stars.
This galaxy also hosted several other supernovae recently, the latest just this year, but that one has become much fainter than what I'm able to photograph. The usual frequency of supernovae in most galaxies is more like one every 100 years or so, so it's pretty unusual to get so many. Our Milky Way Galaxy is way overdue for a supernova though, by several hundred years, so keep watching the sky!37 exposures, 4 minutes each (108 min. total), ZWO ASI294MC Pro camera (cooled to -15ºC, gain 150, dark, flat, dark flat frames), Nikon 80-200mm f/2.8 lens @200mm, iOptron CEM25P drive, ASIAir controller, processed with AstroPixelProcessor, Lightroom and Photoshop.

This 3-part mosaic covers a spectacular region of the constellation Vulpecula and was a very enjoyable summer project: the 'Coathanger Cluster,' the 'Loch Ness Nebula,' and many more LDNs and LBNs, which seem to float on an endless sea of stars.
The 'Coathanger Cluster' (also known as Brocchi's Cluster or Collinder 399) is an asterism of 10 stars. Of these, 6 stars appear to be lined up, but it is believed that the stars are not gravitationally bound to each other.
Several LDNs and LBNs (LBN 133 & 134, LDN 768, 769, 772, 773, 774, 775, 779) form the dark nebula structures that stand out against the starry backdrop and resemble the shape of the 'Loch Ness Monster.'

Mars in conjunction with the Pleiades (M45) taken at Kelling Heath Spring Star Party. This object was very low so the raw images suffered from gradients from the 'claggy' atmosphere at low elevations and from the tops of the trees encroaching in the image as streaks of dark blurs. These were fixed using Astro Pixel Processor (a trial version but based on this I will be buying it as it is significantly better (but slower and more complicated) than the free Deep Sky Stacker.

The Pinwheel Galaxy, also known as Messier 101 (M101), is one of the best known spiral galaxies in the night sky.
M101 is a grand design spiral galaxy (a spiral galaxy with prominent and well-defined spiral arms) located in the constellation Ursa Major, the Great Bear. It is about 170,000 light years in diameter, which makes it roughly 70 percent larger than our galaxy, the Milky Way.
It is approximately 20.9 million light years distant from Earth, which means that we are seeing it as it was about 20.9 million years ago.

M106, also known as NGC4258, UGC7353 and PGC39600.
"Messier 106 is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. M106 contains an active nucleus classified as a Type 2 Seyfert, and the presence of a central supermassive black hole has been demonstrated from radio-wavelength observations of the rotation of a disk of molecular gas orbiting within the inner light-year around the black hole."

At 9hr20 the OIII signal was still very weak and tricky to process, requiring a lot of noise-reduction trickery. I'll definitely have to return to this target again.
The colour palette is particularly weird. Normal HOO tends to be strident reds and blues; HaHOO makes for paler yellow-gold and cyan colours. After a bit of playing around, this formula of my own gives excellent cold blue-green tonality instead.

Centaurus A is located about 11.5 million light years from Earth. It took light 11.5 million years to make its long journey to Earth. NGC 5128 is located in the Virgo Cluster of galaxies near to our Local Group of galaxies. The galaxy is about 60,000 light years in diameter which is about 60% the diameter of our Milky Way Galaxy. NGC 5128 is located in the skies of the southern hemisphere. It appears as a greyish smudge that is easily visible in a pair of binoculars in the night sky.
The Centaurus A Galaxy is considered to be two galaxies in mid-collision. One galaxy is elliptically shaped (spherically shaped) and the other is a spiral galaxy (disk shaped) that is viewed edge-on the Flickr photo. The dark dust band cutting across Centaurus A belongs to the spiral galaxy. The opposite ends of the dust band in the photo have been distorted as the result the of the mutual gravitational tidal forces between the two colliding galaxies.
Centaurus A is an example of a starburst galaxy. Starburst galaxies have a much higher rate of new star formation in them compared to normal galaxies like our Milky Way Galaxy. In the case of Centaurus A, the mechanism that produces the high star formation rate is the increased presence of shock waves in the spiral galaxy’s interstellar medium that is triggered by the gravitational interactions between the elliptical and spiral galaxy during the collision.
Centaurus A has a very active galactic nucleus. This is a sign of a supermassive black hole (SBH) at its center. The SBH is estimated to contain about 55 million solar masses. The activity of the SBH is manifested by two oppositely directed beams of X-rays and radio waves that are almost perpendicular to the spiral galaxy’s disk. The jets extend out to about 70,000 light years from Centaurus A’s center. The jets are generated by the disk of matter, an accretion disk, circling the SBH at such high speeds that it produces a magnetic beam-like structure that focus some of the material in the rotating disk away from the SBH at speeds close to the speed of light. The colliding matter in the jets produces X-rays and radio waves making Centaurus A which makes NGC 5128 one of the “brightest” radio sources in the sky. The jets are not visible in the Flickr photo since the astrograph’s camera detects visible light. X-ray and radio telescopes detect the jets.
The T30 astrograph located at iTelescope’s Siding Spring Observatory in New South Wales, Australia was used to acquire imaging data from NGC 5128. T30 is a remotely controlled robotic astrograph that is controlled over the Internet by members of iTelescope. The imaging data was download to my home computer in the suburbs of Washington, DC for processing.
T30 consists of a PlaneWave CDK20 telescope and a Finger Lakes Instrumentation FLI PL6303E Monochrome CCD camera. The telescope is 508mm (20 inch) diameter and has a photographic speed of F/6.8. AstroDon Luminace, Red, Green, and Blue filters were inserted between the telescope and camera to produce the images needed to be combined to produce the single true color Flickr image of NGC 5128. At total of 3.8 hours of 5-minute exposures were combined using Astro Pixel Processor and PixInsight (PI) dedicated astrophotography software programs on my home PC. Adobe Photoshop 2021 was used to make tweaks in color and saturation to the output of the PI image.
The American astronomer Beverly T. Lynds published her catalogue of bright nebulae. This nebula is listed there as LBN 576, a supernova remnant. The age of the supernova is estimated to be 10,000 years.
The nebula appears as an ionised hydrogen gas bubble, which resembles a cross section through a human brain with spinal cord extension (medulla oblongata), which is why some amateur astronomers gave it the nickname "Medulla Nebula". Other popular names for it include the "Garlic" nebula or the "Popped Balloon" nebula. I'm going with Garlic to spice up the night sky.
The object is very faint. I saw nothing with my Seestar so this image took me three hours to capture with my William Optics ZenithStar 81 APO telescope.

The Virgo cluster is a cluster of galaxies located approximately 59 ± 4 million light-years away in the direction of the constellation Virgo. It contains some 1,300 known galaxies, although there may be as many as 2,000, and forms the central region of the Local Supercluster, in which the Local Group is also found. Its mass is estimated to be 1.2×1015 MS up to about 8 degrees from the center of the cluster, which is equivalent to a radius of about 2.2 Mpc.3
Many of the bright galaxies in this cluster, including the giant elliptical galaxy Messier 87, were discovered in the late 1770s and early 1780s and later included in Charles Messier's catalogue. Described by Messier as starless nebulae, their true nature would not be discovered until the 1920s.
The cluster subtends a maximum arc of about 8 degrees centered on the constellation Virgo, and many of its galaxies can be seen with an amateur telescope. Its brightest member is the giant elliptical galaxy M49, but the most notable and famous is the galaxy M87, located in its center.
In the center of the image we show we have NGC 4435 and NGC 4438, also known as the Eye Galaxies or Arp 120, they are two galaxies in the Virgo Cluster, about 52 million light years from our galaxy, also visible with amateur telescopes.
NGC 4435:
NGC 4435 is a barred lenticular galaxy showing a ring of dust around the nucleus. Through studies carried out with the Spitzer telescope, a young stellar population has been detected in its center, which indicates that 190 million years ago it suffered a stellar outbreak perhaps caused by an interaction with NGC 4438, and almost all of its hot gas, according to studies. made in X-rays with the Chandra telescope, is concentrated in its central region. It also seems to have a long tail that was also thought to be produced by this event, but which is actually a system of dust clouds in our galaxy that is totally unrelated to NGC 4435.
NGC 4438:
NGC 4438 is a hard-to-classify galaxy that has been classified as both a spiral galaxy and a lenticular galaxy, which explains its inclusion in Halton C. Arp's Atlas of Peculiar Galaxies. It is one of the most notable galaxies in the cluster due to its highly distorted appearance, which shows that it is undergoing or has undergone gravitational interactions, and for the unknown mechanism that causes its central region to show activity, and that it has expelled opposing gas loops at one the other. A starburst, a black hole, or an active galactic nucleus has been thought of, and all possibilities are under investigation. It also shows a low content of neutral hydrogen, perhaps due to its friction with the hot gas that fills the intergalactic medium of Virgo or with the corona of hot gas that surrounds the nearby galaxy M86 and/or due to having been torn away by gravitational attraction. of some galaxy with which it was about to collide (perhaps M86 itself), in addition to a displacement of the different components of its interstellar medium (neutral hydrogen, molecular hydrogen, hot gas, and interstellar dust, which reaches up to a distance of 4-5 kiloparsecs from its disk) in the direction of NGC 4435 -which tends to be attributed, however, to friction with the aforementioned intergalactic medium-, and finally traces of having undergone several bursts of star formation.
A pair of interacting galaxies?
NGC 4435 and NGC 4438 have been and are considered by numerous authors to be a pair of interacting galaxies, having calculated that the two galaxies came close 100 million years ago to just 16,000 light years from each other. In any case, and despite the strong evidence in favor of an interaction between the two, other scientists have expressed doubts as to whether the two galaxies are actually interacting despite their apparent proximity, since their redshifts are different and NGC 4435 is barely visible. has suffered the effects of such interaction. It has also been speculated that NGC 4438 may actually be two galaxies merging, having nothing to do with NGC 4435, which has interacted in the past with M86 (to which it seems to be joined by filaments of gas and in which it is detected certain amount of interstellar dust and atomic and ionized hydrogen that seems to come from NGC 4438, which reinforces this possibility) causing the peculiarities observed in it, that the three mentioned galaxies have interacted with each other, and even that NGC 4438 may be being torn apart by the gravity (tidal forces) of M87, which is only 58 arcminutes away from it (and seems to have gotten as close as 300 kiloparsecs).
